MINEOLA, N.Y. (AP) — Lucille Conlin Horn weighed barely 2 pounds when she was born, a perilous size for any infant, especially in 1920. Doctors told her parents to hold off on a funeral for her twin sister who had died at birth, expecting she too would soon be gone.

But her life spanned nearly a century after her parents put their faith in a sideshow doctor at Coney Island who put babies on display in incubators to fund his research to keep them alive.

The Brooklyn-born woman, who later moved to Long Island, died Feb. 11 at age 96, according to the Hungerford & Clark Funeral Home. She had been suffering from Alzheimer’s disease.

Horn was among thousands of premature babies who were treated in the early 20th century by Dr. Martin Couney. He was a pioneer in the use of incubators who sought acceptance for the technology by showing it off on carnival midways, fairs and other public venues. He never accepted money from the tiny babies’ parents but instead charged oglers admission to see the babies struggling for life.

Horn and her twin were born prematurely. She said in 2015 that when her sister died, doctors told her father to hold off on a funeral because she wouldn’t survive the day.

“He said, ‘Well, that’s impossible. She’s alive now. We have to do something for her,'” Horn said. “My father wrapped me in a towel and took me in a cab to the incubator. I went to Dr. Couney. I stayed with him quite a few days, almost five months.”

Couney, who died in 1950 and is viewed today as a pioneer in neonatology, estimated that he successfully kept alive about 7,500 of the 8,500 children who were taken to his “baby farm” at the Coney Island boardwalk. They remained there until the early 1940s, when incubators became widely used in hospitals.

He also put infants on display at the World’s Fair and other public venues during his career. There’s no estimate on how many still are alive today.

Horn worked as a crossing guard and then as a legal secretary for her husband. She is survived by three daughters and two sons. She said she met Couney when she was about 19 and thanked him for what he had done.

“I’ve had a good life,” she said in 2015.

After a funeral Tuesday, she was buried at the Cemetery of the Evergreens in Brooklyn, next to her twin sister.
